Belkin Wemo Binding

[Philipp Hug]

Hi,

I started working on a Belkin Wemo Binding. I used the UPNP code for Sonos and ripped out the stuff, I don't need.

Unfortunately the Wemo is not quite UPNP compliant. I found the following mistakes:

* mime-type of icon is 'jpg' instead of 'image/jpeg'

* one of the scpd files start with a UTF-8 BOM (byte-order-mark) which is not recommended and the UNPN library doesn't like it

* the scpd files are completely inconsistent: e.g variables not declared, or multiple values defined as retval. here's some output:

00:03:43.809 WARN  o.t.cling.model.meta.Action[:174]- Only one argument of action 'ShareHWInfo' can be <retval/>

00:03:43.812 WARN  o.t.cling.model.meta.Action[:174]- Only one argument of action 'SetMultiState' can be <retval/>

00:03:43.835 WARN  o.t.cling.model.meta.Action[:174]- Only one argument of action 'SetLogLevelOption' can be <retval/>

00:03:43.840 WARN  o.t.cling.model.meta.Action[:174]- Only one argument of action 'ChangeDeviceIcon' can be <retval/>

00:03:43.854 WARN  o.t.cling.model.meta.Action[:174]- Only one argument of action 'GetServerEnvironment' can be <retval/>

00:03:43.868 WARN  o.t.cling.model.meta.Action[:186]- Argument 'ServerEnvironmentType' of action 'GetServerEnvironment' is <retval/> but not the first OUT argument

* in one of the scpd files, the argumentList misses the argument element. Good thing here is, that we don't need that one.

So to make it work, I had to patch the first 3 issues within cling, I'll post my findings also to the cling ML and to the Belkin support forum.

Now to my question: How should the item statement for a networked power switch look like?

http://www.belkin.com/us/wemo-switch

The main function is a on/off switch, but it also has other options like time sync, get/set friendlyname, firmware update, ... of which some might be useful in the future.

I currently use the following syntax:

Switch mylamp "Lampe Ikea" (Wemo,GF_Living) {wemo="[Socket-1_0-221238K11009FA:binarystate]"}

should I change this to:

wemo="[Socket-1_0-221238K11009FA]"}

?

Hi,

should I change this to:

wemo="[Socket-1_0-221238K11009FA]"}

Yes, I would suggest to change it, because when being bound to a Switch item, the switching functionality is the only meaningful thing to do - so referring the socket by its id should be enough as a binding configuration (actually, you could also leave out the square brackets, right? I.e. only do { wemo="Socket-1_0-221238K11009FA" })

I would agree with Kia. I would also suggest looking at the plugwise and zwave binding topics. Would be nice for all "power" devices follow a similar schema.

Hey guys - just wondering what the state of this binding is? Is the code available anywhere?

[Philipp Hug]

Hi,

The binding is working, but it needs some clean up and a patch in a dependency before merging.

I'll upload it somewhere tonight.

Hi Philipp,

Were you able to upload it somewhere?

Got couple of those switches, I'd like to try it.

Thanks

Hi,
any news on this topic?
Just got a WEMO today and would like to try your binding.
Using external python stuff is not my preffered solution.

Hi,

In case you didn't see my post to the cling mailing list:

Cling Patch:
* Ugly hack to not crash on missing Icon and not verififying schema.
* this needs to be cleaned up into a mergable patch for upstream
http://people.debian.org/~hug/cling-1.0.5-source-wemo.patch

Openhab wemo binding:
* copy-paste of sonos binding, needs to be cleaned up and copyright
headers adapted.

Hi,
I received a Wemo for xmas and I'm looking forward to the integration.
Kind regards,
Neil.

Hi,
There is another user working on a wemo binding called gitaaronc. Reference can be found on cling mailing list.
Aaron is trying to clean his code to have it ready for the next release.
